Earlier this year, a South Korean crypto exchange suffered a security breach, with attackers draining approximately $35 million in various cryptocurrencies from its hot wallets in just 15 minutes. The incident highlights the evolving sophistication of exchange attacks and the critical need for advanced detection systems. Here are the key details:

• The attack targeted multiple hot wallets across hundreds of transactions, showing patterns consistent with wallet signing compromise rather than smart contract bugs.
• Despite freezing approximately $23M in LAYER tokens, the exchange was unable to recover the remaining stolen assets.
• The breach reflects a growing trend of attacks against exchanges and custodians managing complex multi-chain withdrawal systems.
• Real-time detection of anomalous wallet behavior, including drain-to-zero patterns and transaction burst activity, could have limited losses.
